Luggage and bags:
Light weight and something you can maybe lock up, when left in room or traveling.
Clothing/Shoes/Weather Gear: Light clothing for sure, good quality sandles or walking shoes.
Toiletries and Medical Supplies: Maybe a small medkit just in case.
Photo Equipment: Camera of some kind.
Camping/Beach/Outdoor Gear: Baseball or frisbee. Also saw some people playing soccer (football) on the beach.
Miscellaneous: Sunscreen and sunglasses are a must if you are like me, and burn easily.
